e it known that FRANK G. SCHENUIT, a een oit tie United States, residingat timore, in the State ci! Maryland, has in- -d ccrtainnew and usefulimprovements Y aire Casinge., o which the following is a specification.'

Aihis invention relates to improvements in o einge for pneumatic timeand has for its obto provide an improved side-Wall conuction fortire-caeinge which will maieriaiiy strengthenand i'eeniorce the side.

1avail against Wear Tvhen traveiing on roads 'Vch contain rn'ts andstones; which will protection against damage by curbs 1-ing paraiiei toa side-Walk and i; materiai decrease damage caused l ,3f of the casingfrom friction durnff travei over a road.

i?? e invention is iliustrated in the accom- F drawing, Wherein,- showsa portion or" the casing in side g. 3. shows a sectioned detaii througha agnient of the side Wall of the casing?, as aine Would appear if cuton the line cle fg, me ci;

to the drawing the numeral 5, c inner face o'i the casing which rote vesthe pneumatic tube; 6 the fiange or head hy which the casingis heldahout la eelriin; 7 designates the side Waii ci'. the and 8 the treadci' 'the saine, r

in iai' ae my present invention is conn cemedf, it immaterial as to howthe intehe casing walls are made or huiit up.

. l is, i ineen that my invent-ion has nothinwf to do with theinternalconstruction oi? the casing as to its plies or the er of t l5,1922. Serial No. 660,992.

I ln the preferred embodiment oi my inventlon, l provide a greaterthickness of rnhher at the tread 8 and adjacent to the side edges ofthe'latter than at the side Walls 7., and @0 at the ypoint where theside Walls and the tread join, form a slight annular concavity 9 whichproduces an annular ridge i0. F rom this ridge l0 end extending acrossthe side wall toward the annular Harige or .bead

6, provide a series ot corrugations or rihs The outer ends 12 of theseribs terminate at the side of the annular rid'e l0 and in the concavity9 so that no shoulder is formed 10 at the ends of the ribs adjacent tothe tread.

The corrugations er ribs employed by me are not annular endless headsbut are ribs or corrugations that extend in a direction cross- Wiee oi?the casing and more nearly at right angles to a given point on thetread.

it may he said that my improved corrugations or ribs ll extend radialiyalong the sides from the center of the casing toward the tread but it isto he understood that e0.

these corrugatione or ribs may incline or extend somewhat on a tangentwith respect to the annuiar concavity 9 and ridge 1G, in-l stead oi"being 'concentric with respect tod either the inner or cutercircumferencee ot e5 the casing.

fis a matter ot fact, the series of rihs'or corrugations 11 formed onthe side Walls by nie are so disposed that their lines of direction, ifcontinued, would cross both the in ner and cuter circumferential linesof the casing.

Si e ivalis of a tire-casing having the se ries of ribs or corrugationsarranged in ac'- cordance with my invention, aii'ord no 95 shouiders orprojections parallel or concentric with the tread to he cut or chippedcd by the Walls of a rut or by stones or other devices iying on the roadimmediately at the sides of that portion of the tread which is inContact With the road.

Moreover, my sci-caiied radiailyerranged 'ribs or corrugations'sweeparound With the casing and cnt through the air in a Way that Wiiimateriaily assist 'in 'cooling the vvail- 195 surfaces.

Having described my invention, I claim,- l. in annuiar casing :forvehicle tires hav ing a thickened thread around its outer circumferenceand provided With eide Walls llo each "t which has an annular dange orbead around its inner circumference, said casing also having e, seriesof ribs projecting'from its outer side Wall surfao Whlch ribs ex-`Jeend. in a, direction from the base of the ange or bead toward butterminate at the side edge of the thickened annular tread. 2. An annularcasing-for vehicle tires having a trend surfaceat its outercircumference and also having side walls each of which has 2L Harige orbead around its inner circumference, the outer faceof euch side Wallbeing' provided with a continuous series of short4 side ribs the outerends of which ribs terminute adjacent to the tread surface and extendtoward the ange or bead .at the same Iside' of the casing.

and provided with sie 11H557 each side Hang@ or wail of the casing boingsevziraed from the annular tread surfe@n by an annular ridge ut the naseor the tread and earch of said side walls of the casing beineh providedwith `a Continuous series o" ribs Whose outer ends; terminate saliciannniar ridge said ribs extendinginward anni ierniinuting ur the buse ofdie Hang@ yor bead @u the inner ciruinnferenee oihe @side wall ov theeasing.
